A sensor includes a heater, a thermal insulator between two thermometer layers, the heater generating a thermal gradient within the thermal insulator. The thermometers give an indirect measurement of fluid flow around the sensor, based on their temperature readings. The thermometers are flexible layers including gels.

ABA type block copolymers as a new class of temperature sensing polymers with tunable, high temperature coefficient of resistance (TCR). A sensor includes a heater, a thermal insulator between two thermometer layers, the heater generating a thermal gradient within the thermal insulator. The thermometers give an indirect measurement of fluid flow around the sensor, based on their temperature readings. The thermometers are flexible layers including ABA block polymers.

ABA type block co-polymers for temperature sensing and flow meters

A composite includes a polymer network including pectin or a pectin derivative; a low-molecular compound having a hydrophilic group in the polymer network; and a polyvalent metal ion coordinated with an anion present in the polymer chain of the polymer network.

A temperature sensor is described, which includes a sensor gel having a polymer, water and ions, and a first and a second electrode separated from each other by the sensor gel. The present disclosure further relates to a system which has a temperature sensor, a voltage source or electric current source, and a measurement device for detecting voltage or electric current. The present disclosure further relates to a bolometer and a temperature sensor array. A method for temperature detection is also described, wherein a temperature sensor is provided, a voltage or an electric current between the first electrode and the second electrode of the temperature sensor is provided, an electric current or a voltage between the first electrode and the second electrode is measured, and a temperature is determined from the measured electric current or voltage.

Gel based thermal sensors

A haptic device can be realized with a single acoustic actuator controlling multiple unit cells by having the unit cells be composed of cantilever arms with different resonant frequencies. The unit cells can be further improved by having the cantilever arms be in a spiral shape, and more specifically an Archimedes spiral shape.
